Samsung Galaxy Z Flip8 (SM-F776U1) Firmware Overview
What is the latest SM-F776U1 firmware?
F776U1UES3AZIL, released September 28, 2026 with Android 17. It is a security update on bootloader binary 3. The archive holds 53 official builds across 13 regions (CSC).
Is the Samsung Galaxy Z Flip8 still getting updates?
Yes. The newest build is from September 2026, and 13 of 13 regions already have a build from that month; the rest usually follow within a few weeks.
Can I downgrade the SM-F776U1 firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. In the archive the binary of this model rose from 1 to 3:
- Binary 3 — since Sep 2026
- Binary 2 — since Aug 2026
- Binary 1 — since Jun 2026
A phone already on binary 3 rejects builds with a lower binary in Odin ("SW REV CHECK FAIL"), so it can go back to an earlier Android version only if that version has a binary 3 build. How to read a build number.
